Trunk Group Load Sharing
When you configure a trunk group, you specify whether the trunk group is a "switch" trunk group or a "server" trunk
group:
• Switch trunk group – Use this type of trunk group to connect one Foundry Layer 2 or Layer 3 Switch to
another Foundry Layer 2 or Layer 3 Switch.
• Server trunk group – Use this type of trunk group to connect a Foundry Layer 2 or Layer 3 Switch to a file
server or single host device.
The Foundry device load shares across the ports in the trunk group. The type of load sharing depends on the type
of device. Table 10.5 lists how Foundry devices load share traffic across the ports in a trunk group. Notice that
the load sharing methods differ on Chassis devices and Stackable devices for server trunk groups on Layer 3
Switches.
